Running KDE Neon 18.04, since an update sometime in october, I've been noticing
huge slowdowns with Dolphin also, I was out of country for a while so I had a
big backlog of updates and can't nail down exactly when it started, am
currently up to date on all packages.

I average 6ish tabs open in dolphin, after some days, maybe only hours of
general usage, I can see the dolphin process spike to 100% cpu when I am
hovering over files, the animation of hovering over the files is also very
lagged like its really struggling, the cpu spiking will stop if i dont move the
mouse, and resume as I hover over another file, even simple small txt files.
The same behavior is seen when switching tabs as well.

I tried closing all tabs down to just 1 and it was noticeably better bug still
laggy, only after fully restarting dolphin did I get normal fast performance
again. I opened up a bunch of tabs (6) to various folders I work in and was
still fast since the restart.

I'm a programmer but not experienced in linux development, but this feels like
a resource build up occurring that isn't getting cleaned up, causing heavy cpu
work just to do basic things.

I'd be happy to try debugging or monitoring logs as the issue returns but at
the moment I wouldn't know where to start in that regard xD.

Software:
dolphin 18.08.3
plasma 5.14.4
frameworks 5.52.0
qt: 5.11.2
kernel: 4.15
